The White Shoulder Caps FOR Armless Female Mannequins (mannequin not included) are a component of our Mannequin Systems. Create a mannequin by selecting a bust and legs with a base, then choose shoulder caps or one of three different pairs of arms. The System Mannequin Series is a revolutionary, component based approach to mannequin design. Use the male shoulder caps when using armless female mannequins to create a finished look.
